Issue logging into personal teams account on iPhone

Simon Blakeley 0

I am having trouble logging into my personal microsoft teams account on my iPhone. My work account is working perfectly, but having used my personal account in the past (and then logging out) I can no longer login. I get so far and then when taken to the microsoft login browser page it tells me there is an error and I have tried to login too many times. I have left this alone for longer than 24 hours and I am still having issues. Here is what I have tried so far:

Logged out completely of all Teams accounts.
Deleted the app from my iphone.
Re installed the app.
Tried logging into my personal account first.

This hasn't worked either. Any suggestions please?

Hi Simon Blakeley,

To help narrow this down, could you please clarify a few points?

Are you able to sign in to your Microsoft account successfully at https://account.microsoft.com using Safari on the same iPhone?
Can you sign in to Teams Free using the same personal account on another device (for example, a PC, Mac, or another mobile device)?
What is the exact error message you receive on the Microsoft sign-in page? A screenshot (with any personal information obscured) would also be helpful.
Does the issue occur on both Wi-Fi and mobile data?
Is two-step verification enabled on the affected Microsoft account?

The answers to these questions will help determine whether the issue is related to the Teams app, the iPhone's authentication process, or the Microsoft account itself.

I look forward to your update.

Hi Simon Blakeley,

Thank you for the update.

I'm sorry you're continuing to experience this issue. I understand how frustrating this must be, especially since your personal Microsoft account can sign in successfully through the browser and Teams is working correctly on your other devices.

Based on the information you've provided so far, the issue appears to be isolated to the Teams sign-in process on this particular iPhone rather than a problem with the account itself.

Since you have already tried the common troubleshooting steps, including signing out, reinstalling the app, and waiting more than 24 hours, it may be worth allowing a bit more time before trying again. In some cases, sign-in related issues can be tied to temporary service-side authentication delays that take longer than expected to clear.

I realize this is probably not the answer you were hoping for, but given the troubleshooting already completed and the fact that the account works elsewhere, waiting a little longer is the most reasonable next step at this stage.

I'm sorry for the inconvenience, and I appreciate your patience and understanding. Thank you for taking the time to provide the additional information and work through the troubleshooting steps.
